Problems solved by technology

The purpose of this method is to improve the absorption and fixation efficiency of carbon dioxide and reduce energy consumption. The proportion of added humate is relatively high, but it is not easy to operate, and the alkalinity is strong, which easily leads to the volatilization loss of nitrogen.

Abstract

The invention relates to a humic acid synergistic ammonium bicarbonate fertilizer and a production method thereof. The ammonium bicarbonate fertilizer comprises the components in percentage by weight as follows: 0.15%-0.60% of a humic acid synergist and 99.40%-99.85% of ammonium bicarbonate, wherein the content of the humic acid accounts for 0.09%-0.4% of the total weight of the humic acid synergistic ammonium bicarbonate fertilizer. Compared with ordinary ammonium bicarbonate, the humic acid synergistic ammonium bicarbonate fertilizer has the characteristics that the fertilizer is good in yield-increasing effect, high in nutrient utilization rate, environment-friendly and the like. At the same time, the production technology is simple, the cost is low, raw material sources are wide, the operation is easy, the industrial promotion is facilitated, and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural chemicals. More specifically, the present invention relates to a humic acid synergistic ammonium bicarbonate fertilizer, and also relates to a production method of the humic acid synergistic ammonium bicarbonate fertilizer. 【Background technique】 [0002] For a long time, low fertilizer use efficiency and its environmental risks have been the focus of people's attention, and the negative impact of chemical fertilizer application on the environment is becoming more and more serious. Countries all over the world have gradually realized that the development of new slow-release fertilizers with high utilization rate is one of the most effective ways to improve nutrient use efficiency. Since the 1960s, the research and development of various new fertilizers aimed at improving the utilization rate of fertilizers has become a research hotspot in the field of fertilizers in the world. Throughout ...
